HA! While I was waiting for you (and others) to reply, I found Aerotanks. They make a 40 gallon one specifically for an E350 Quigley -- though the caveat is that maybe they're not smog legal in Kalifornia. I will put a call into them in the morning.http://www.aerotanks.com/inventory/e250-350.html

Maybe my tank is larger than 21 gallons -- I've never run it dry. I fill it up when the needle gets uncomfortably close to "E", but maybe there's 9 gallons still left. (I've read here and elsewhere that the fuel gage becomes somewhat unreliable (with regard to Empty) after being cut down for the Quigley installation. I suppose I need to run it out of gas to know where the real bottom of the tank is ...)

Thanks!

Note: to be smog legal you will also have to install a 2nd Evap canister, as the stock one is only good for 35-gallons. If AeroTanks isn't able to provide a CARB sticker, you might to stick with TransferFlow, which would require install at QuadVan. I've heard of others having problems with aftermarket fuel tanks missing certification stickers.

Oops, I didn't notice you are in Ca. I think you're going to get bad news from Aerotanks. Good luck though. Also, this is actually a diesel tank, which they can modify for gas, or at least they did for me and a few others. But, I don't think they can certify it or whatever. It amazes me that people in Ca don't just ride bicycles everywhere. What you have to do to keep a car on the road legally is stupid.

Oh, Aerotanks 40 gallon tank is really 45, or even more some have reported. Good luck!

Thinking about the CA smog issue: In previous smog checks on other vehicles, I don't recall the tech looking at my fuel tank as part of the inspection. Occasionally, I get a fuel cap pressure test, but nothing else. More to the point, how are my regulators gonna know/care if the tank I have is factory-installed, or a series or washed-out jelly jars, or anything else?

We are a dealer for Aero Tanks and have installed a few - I have one in my V10 E350 that is registered in South Dakota and lives in Baja.

Their replacement tank is advertised as being a 45 gallon tank - I got 49.5 into mine on first fill.

Areo Tanks do not have a CARB (California Air Resources Board) approval number for use in gasoline vehicles so they only sell diesel tanks in CA.

The 45 gallon tank will not fit in 4x4 conversions like Quigley and several others who use an extension housing on the back of 2wd transmissions before the transfer case. These extensions are used instead of converting the transmission to the shorter 4x4 output shaft.

This setup leaves seven less inches for the fuel tank and is why they cut the factory tanks back and lose so much capacity.

What Aero and we can do is cut seven inches off the tank and re-weld it. Jacob at Aero just did this on a van that we installed a Max RIP Kit on. It was the first one that he had to do and we had some discussion about it - these will be sold as 40 gallon tanks.
